摘要： A system and method for engineering loss in a physical system by steering parameters of the physical system to the vicinity of an exceptional point is disclosed. In the vicinity of an exceptional point, localization of the fields helps to enhance any linear or nonlinear processes. As examples loss-induced transparency in the intracavity field intensities of coupled resonators, loss-induced suppression and enhancement of thermal nonlinearity in coupled resonators and loss-induced suppression and revival of Raman lasing in whispering-gallery-microcavities are demonstrated.

摘要： Embodiments of the invention provide Raman spectroscopy methods and devices that exploit high quality factor (Q) resonators to enhance Raman signal by several orders of magnitude over the signal typically expected for Raman methods. Embodiments typically include one or more resonators, typically microtoroid microresonators. Embodiments also take advantage of Rayleigh scattering using these microresonators. Embodiments may be particularly useful for non-labeled nanoparticle sensing.

The system includes an optical assembly that includes a first dissipative optical system and a second optical system coupled in energy transfer communication with the first optical system. The second optical system is configured to receive a continuous flow of energy from an external source and to transfer energy to the first optical system through the couple wherein the energy transferred to the first optical system from the second optical system is approximately equal to the energy dissipated in the first optical system, where the energy transferred to the first optical system from the second optical system is selectable using at least one of an amount of couple between the first optical system and the second optical system and a gain of the second optical system.
